It turns out the issue also exists in the latest mainline kernel!

The fix "x86, pageattr: Prevent overflow in slow_virt_to_phys() for X86_PAE" is there, but a later patch "x86/mm: Fix slow_virt_to_phys() to handle large PAT bit"
 (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=34437e67a6727885bdf6cbfd8441b1ac43a1ee65)
actually removed the fix unintentionally, so we have the regression...

I have made a new fix and post it to LKML just now (<email address hidden> was Cc-ed):
